Participants

Reaction Steps

A solution of 10.00 g. (0.0359 mole) of 2-chloro-3,5-dinitrobiphenyl in 200 ml. of dioxane is hydrogenated at 3 atmospheres of hydrogen using Raney nickel Catalyst. The catalyst is removed by filtration and the filtrate is concentrated under reduced pressure. 110 ml. of benzene is added to the residue and this is removed by distillation. The resulting oil is used directly in the following reaction.
